MACHINERY FOR TAKING AND LAYING PAPER FROM THE CUTTING-ENGINE.

Specification of Letters Patent No. 6,337, dated April 17, 1849.

To all 101mm t may concern.'

Be it known that I, JOHN M. HOLLINGS- WORTH, of Milton, in the county ofNorfolk and State of h/Iassachusetts, have invented a new and usefulmachine for receiving paper from a paper-making engine or othercontrivance and piling or laying it in sheets one on the other, whichmachine I herein term an automatic lay-boy; and I do hereby declare thatthe said machine is fully described and represented in the followingspecification and accompanying drawings, letters, figures, andreferences thereof.

Of the said drawings Figure 1, represents a top view of the saidmachine. Fig. 2, a side elevation, Fig. 3, a central vertical andlongitudinal section, and Fig. 1, an end elevation of the same.

In the said drawings A, represents a frame by which certain of theoperative parts of the machine, are sustained in their respectivepositions.

B, C, D, denote three posts, or a part of the framework of a commonengine or machine for making sheets of paper from pulp.

E, denotes the rotating knife of said paper engines, the said knifebeing made to act in connection with a fixed or stationary knife (notshown in the drawings) and in such manner as to separate the sheets ofpaper from the web of paper as fast as it is produced by and proceedsfrom the paper making engine. The said knife E, is secured at or nearits two ends to two circular heads, F, Gr, or other suitableequivalents, affixed to a horizontal shaft H, the journals of said shaftbeing supported in suitable boxes I, K. The said rot-ary knife, and thesaid stationary knife, are devices well known, and in common use onordinary paper making engines; the web of paper after being made by theengine, being caused to pass between the said two knives at a regularvelocity, and to be cut up into sheets, by the action of the saidknives. .In rear of the said rotary knife and below it, and in aconvenient position to receive between them the lower end of the sheetof paper, two rollers L, M, are arranged. The said rollers are placedwith their axes parellel to one another, and to that of the shaft of therotary cutting knife, as seen in the drawings. Somewhat in advance ofand below the shaft of the rotary cutting knife is another roller N,whose journals a, are supported by and revolve in bearings made in theouter ends or parts of two arms O, P, projected from the two posts B, O.Around the two rollers L, and N, and passing under the roller M a seriesof any suitable number of endless tapes or bands R, R, R, is made tooperate; each of the said bands or tapes being made to pass about therollers, as seen in the drawings.

IVhen the rear ro-ller L, is put in revolution in the direction denotedby the arrow in Fig. 3, it at the same time puts in motion theseveralendless tapes or bands, and as the web of paper which passes overthe fixed knife, descends its lower edge is caught by or receivedbetween the endless tapes, and the roller M, which operating togetherdraw the sheet `of paper between them and remove it from the web, assoon as said sheet is sepa rated from the web by the knife. The sheetnext passes from the roller M, to the roller N, toward which it iscarried on and by the several endless tapes, and from thence it drops orfalls upon a table or platform S, which in due time is brought into aproper position to receive the sheet.

rI'he said table S, or platform is arranged upon the horizontal ways c,(l, of the frame A, and is so applied to the said ways and sustained bythem as to be capable of being alternately moved backward and forward ina longitudinal` direction that is in a direction first toward and neXtaway from the series of endless tapes or bands. On the upper surface ofsaid table are four ledges, rules, or strips of metal e, f, g, 7L, oneof which c, is fixed firmly to the rear edge of the table, while each ofthe three others is attached at right angles to one of three plates z',7c, Z, provided with slots m, mi, m, and set screws a, u, n, which passdown through the said slots, and screw into the table; the aforesaidcontrivances being such as will enable a person at any time to regulatethe distance of either of the two ledges f, g, or e, 7L, asunder. As theweb of paper previous to being cut into sheets, is generally divided inthe middle by another knife suitably placed, a fixed ledge 0, may beplaced on the table and between and parallel to the two ledges f, and g,as seen in the drawings, the two spaces g, r, between said ledge o, andthe ledges surrounding it, conr) tcm stituting two shallow boxes orreceptacles to catch the paper when it is discharged from the endlesstapes or bands above set forth.

Having thus specified the elements of my invention, I shall now proceedto describe the machinery by which they are caused to perform theirrespective duties, T, is a main driving shaft whose ournals aresupported by and revolve in boxes U, U, afiixed to the posts C, D, asseen in the drawings; power to rotate said shaft being applied to it inany proper manner. On the inner end of said shaft is a small spur geart, which engages with another spur gear u, fixed upon the rotary knifeshaft; the said spur gear t, when revolved by its shaft, being made tocommunicate motion to the other spur gear, and in such manner as torevolve the shaft and rotary knife. The shaft T, has another and largerspur gear V, fixed upon it, so as to be rotated by and with it. The saidgear V, engages with a small pinion W, fixed upon a horizontal shaft X,arranged as seen in the drawings, and made to revolve in suitablebearings. On said shaft X, is a pulley Y, around which and the mainroller L, an endless beltor band Z, is stretched and made to operate,the said band serving to put in mot-ion the system of rollers, andendless tapes. Y

On the inner end of the shaft X, is a small sprocket wheel A2, aroundwhich and a pulley B2, disposed with respect to it as seen in thedrawings, an endless chain C2, works. To this endless chain a crank D2,is jointed,- the said crank rod being also jointed to a projection E2,made to extend downward from the movable tables, before mentioned.

The revolution of the chain about the sprocket wheel, and pulley Willimpart to the tables, its proper alternate reciprocating rectilinearmovement; and when the crank pulley, a kind of a jogging motion, or sucha peculiar motion is produced, as serves to lay the sheet of paperreceived on the top of the piles, evenly with respect to the remainderof said pile.

At the time of the separation of the sheet of paper from the web, thesystem of tapes and rollers, should so act upon it, as to draw itsomewhat tightly. The velocity of motion of the table S, shouldcorrespond with that of the tapes or endless bands, and the movements ofthe said table, should be so regulated as always to receive the severalsheets at or over one given place.

I do not always intend to employ for operating the elements of myinvention, precisely such mechanism as I have herein above described, asother kinds well known as a mechanical equivalent or equivalents for anypart or portions of the same, may be substituted, and used, ascircumstances may require. Neither do I intend to give to any or all ofits parts the exact shape or shapes as represented in the drawings, butintend to vary the same in such manner as may be necessary.

What I claim as my invention is- The movable platform, table, or sheetreceptacle S, in combination with the system of endless tapes and theirsupporting rollers, and applied to the paper making en gine machinery,by which the sheets of paper are separated from the web thereof,

and delivered to said system of tapes or endless bands, and rollers, orany other equivalents therefor, or as applied to any contrivance ormachine from which sheets of paper are to be received and evenly packedor piled as above described.

In testimony whereof I have hereto set my signature this seventh day ofAugust, A. D. 1848.

JOHN M. HOLLINGSWORTH.
